Dry reforming theoretical review
WebFeb 15, 2024 · Although ethanol dry reforming is an attractive carbon utilization technology, problems of severe coke formation and low catalytic activity should be solved for realization of the technology. We demonstrate the effects of alkali metal additives (lithium, sodium, and potassium) on nickel catalyzed ethanol dry reforming. Potassium doped nickel catalyst … WebSince fossil and renewable feedstocks can be used, dry reforming might play an important role in the transition of the chemical industry. The produced CO rich synthesis gas can be used in established syngas conversion processes like methanol production, dimethyl ether (DME) or acetic acid synthesis.
